High Precision Square End Mill / CNC Milling Bits 0.2 μM Grain Size Custom
KTC Tungsten Carbide Nano Coated End Mills
Definition
An end mill is a type of milling cutter, a cutting tool used in industrial milling applications. It is distinguished from the drill bit in its application, geometry, and manufacture. While a drill bit can only cut in the axial direction, a milling bit can generally cut in all directions, though some cannot cut axially.
End mills are used in milling applications such as profile milling, tracer milling, face milling, and plunging.
Specifications
E650 Blue / Black nano milling cutter series (< HRC65 °) adopt imported high-quality fine grain tungsten steel material with bending strength of 4500mpa and grain size of 0.2μm, with high-performance composite coating imported from Switzerland. E650 milling cutters is designed with special angle, especially suitable for heat treatment die steel, high-speed, high hardness material processing. With high precision quality control, and full inspection, all E650 series end mills are delivered with 100% qualification rate.
